Sampaio, ?nderson Gon?alves;Souza, Alex Sandro Rolland;
Revista Brasileira de Ginecologia e Obstetrícia , 2010, DOI: 10.1590/S0100-72032010000400004
Abstract: purpose: to determine the factors associated with cesarean section in pregnancies with fetal death at a maternity hospital in recife, pernambuco, brazil. methods: a cross-sectional study was performed, which analyzed data from the information system about mortality and medical records, from january 2005 to december 2008, of hospital bar?o de lucena (hbl). we analyzed women with fetal death diagnosis, with gestational age of 20 weeks or more, in terms of sociodemographic characteristics, causes and types of fetal death, obstetrical precedents and birth characteristics. the associations between the variables were analyzed by the χ2 test of association and fisher exact test, with the level of significance set at 5%. we calculated the prevalence ratio as the measure of risk and the confidence interval (ci) at 95%. logistic regression analysis was also performed and the odds ratio (or) was calculated. results: among the 258 pregnant women with fetal death, 27.5% (n=71) underwent cesarean section. after multivariate analysis, the factors that remained significantly associated with cesarean section were maternal age below 20 years (or=0.23; 95%ci=0.06-0.85), history of one or more cesarean sections (or=7.02; 95%ci=2.29-21.55), multiple gestation (or=9.06; 95%ci=2.01-40.71), use of misoprostol for birth induction (or=0.07; 95%ci=0.01-0.32), fetal death occurring during birth (or=4.01; 95%ci=1.13-14.24), low birth weight (or=0.33; 95%ci=0.11-0.94), presence of hypertensive disorders (or=3.7; 95%ci=1.46-9.39) and abruptio placentae (or=13.9; 95%ci=4.67-41.69). conclusion: in hbl, the risk factors for cesarean section in pregnancies with fetal death were previous cesarean section, multiple gestation, intrapartum deaths, hypertensive disorders and abruptio placentae. the protective factors were teenage pregnancy, use of misoprostol and low birth weight.

Abstract: hypertensive disorders in pregnancy deserve special attention in the setting of global public health. currently, they represent the third cause of maternal mortality in the world and first in brazil. from a practical standpoint, pre-eclampsia remains a syndrome that leads to serious repercussions on maternal and fetal mortality and its etiology is not well known. currently, the best treatment for forms of pre-eclampsia is being discussed at different times in pregnancy and puerperium, with the objective to reduce the high rates of maternal and fetal morbidity and mortality. considering the pathophysiology of the event, anticipation of delivery is the best treatment for pre-eclampsia. the use of magnesium sulfate is recommended in all cases of severe pre-eclampsia and eclampsia for prevention and treatment of seizures. likewise, treatment of hypertensive crises is recommended. hydralazine, nifedipine and labetalol have been the most commonly used drugs for this purpose, but their use depends on the familiarity of the treating physician. antenatal corticoid therapy is indicated whenever there is an imminent risk of preterm delivery between 24 and 34 weeks. in contrast, there is insufficient evidence to recommend bed rest and routine plasma volume expansion, and there is an urgent need for randomized clinical trials to determine whether maintenance antihypertensive treatment in pregnant women has benefits or risks for mothers and fetuses in all clinical forms of disease, particularly in cases of pure pre-eclampsia.

Abstract: osteogenesis imperfecta is a connective tissue disorder due to quantitative and qualitative anomalies in type 1 collagen, genetically transmitted by a dominant or recessive autosomal gene, leading to bone fragility. we report a case of a 19-year-old g1 po patient referred to our institution following a screening ultrasound that demonstrated short limb fetal extremities. a level 3 scan was performed which evidenced an irregular cranial shape and compression of the cephalic pole with moderate transducer pressure. limb shortening, decreased echoes and fractures of long bones were found on our scan evaluation. a vaginal delivery occurred at 35 weeks of gestation. the male newborn, weighing 1.990 grams had 6 and 8 in apgar scores. the neonate was clearly abnormal, presenting irregular cranial shape, with poor ossification on x-ray, blue sclera, fractures and limb deformities. postnatal evaluation was satisfactory and the neonate was discharged in good conditions. prenatal diagnosis is important for an adequate pregnancy follow-up. postnatal outcome was not related to vaginal delivery, as there were no recent fractures in the newborn.
